William, my love,
You have only been gone for two days but yet, I miss you a lot. It's a bit ridiculous, isn't it? I promise I'm not the clingy type. I absolutely love the coffee mug by the way, thank you! It's very punny! As for Mycroft intercepting my last letter to you, he probably won't do that again after the mention of our shared shower. Perhaps we should find him a girlfriend, yeah?
I wish you well during your investigation. I pray that you stay safe. Make sure you come home to me, Sherlock. I have to confess of a bad dream I had last night. I know it's silly, but I still feel a bit scared. There are times that I fear I might suffocate you with my love. Okay, now it does sound silly but you're still getting used to this. It's brand new for you and I just don't want to scare you away. But I must also tell you that I cannot help but find more ways to love you more, to pull you closer and hold you tighter. To keep you safe and protect your heart.
I babysat Rosie yesterday. I took her to the park and we had ice lollies. Sorry for all the crazy texts yesterday. She saw your photo in my contacts and just typed away. It was nice of you to send a photo back to her; nice deduction skills. You're a good godfather for her.
I realize that even I have some emotional growing to do. You showed me that. The one thing I do know for sure is that I've never been so deeply in love. I should say thank you more often, so I'm going to start now. Thank you for accepting and loving who I am. Thank you for not just saying the words but proving them through your actions. Thank you for taking a chance on us even though you were terrified of making that leap. You trusted me enough to catch you on more than one occasion. I never want to let you down.
You once apologised to me for making me wait so long for you. I'm here to tell you that you don't have to apologise for that. You never had to. You, William Sherlock Scott Holmes, are worth the wait. Even if I had to wait until my last dying breath, it would have been worth it just to know that you loved me all those years. For a long time, I was known as the girl who loved too much but I realize now that it's nonsense. There's no such thing as loving too much. As I see you grow with me in this relationship, I am happy to know that the passion isn't one-sided like I'm used to. You are such a passionate human being whether it be about the career path you chose for yourself or the way you show your love. I wish you were here with me now so that I could express myself fully.
Do you have any idea how much I love you? I'm not even sure I know the answer to that, as it cannot be put in words.
With all my love,
Molly xxx
